IMPROVEMENT IN SPARK-ARRESTERS FOR LOCOMOTWES.

Specification forming part of Letters Patent No. 133,656, dated December3, 1872.

CASE B.

and'consists in combining, with a hooded smoke stack, a bi-branchedpipe, through which are forced the cinders, sparks, and smoke-the twoformer into cinder-boxes prepared to receive them, and the latter intothe fire-box.

In the drawing, the figure is a side elevation, partly broken out. 7 I

A in the drawing represents the boiler; B, the fire-box; G,thesmoke-box; l), the smokestack; E, a hood or cover opening out toward thefront of locomotive; and F, a bi-branched pipe connecting with hood,passing down on each side of cab, and connecting with both fire-box "andcinder-boxes G G. 11 is a waterjetpipe leading from feed-water pipe, andemployed to extinguish the fire still burning in cinders after they"have reached boxes. I I are. slat-ioldingbottoms'in the cinder-boxes,

' which are opened at suitable times to allow egress to the cinders.

The operation is as follows: The sparks, smoke, and cinders, passingfrom fire-box and into sin0ke-box,ascend the smoke-stack, and arestopped by the hood or cover E. Being then taken by the draft from thefront, they are carried backward through pipeF and the cinders droppedintoboxes G G, while the smoke passes through pipes f f into-thefirebox. On the under side of pipe F is joined a vertical pipe, J, intowhich the heavier cinders fall bytheir own gravity, and are conveyed tosand-box K,from

whence they may be discharged on the track,

with or without sand.

It is well known that a sand-box is employed on locomotives for creatingfriction on the rails where the latter are wet, or where, for otherreasons, the wheels slip and will not take hold on the rail. Thesesand-boxes are provided with valves or dampers and connecting mechanism,by which a person in the cab may discharge the sand whenever thereis anecessity for it. It is discharged on the rail in front of thedriving-wl'ieels, and is sometimes swept t off by brushes placed behindthe wheels. These sand-boxes require repeated filling, while, byconnecting my pipe 1! by tube with the sand-box K, and emptying thecinders thereinto, no necessity any longer exists for the use of sand,while the supply is automatic,

never-failing, and without the use of hand la her. In pipe F is a sieve,f, which arrests the heavier cinders and directs them into pipe J.

Having thus described my invention, what Iclaim as new, and desire tosecure by Letters Patent, is

1. The smoke-stack D having hood or cover E, combined with pipe F f,cinder-boxes G, and fire-box B, constructed and arranged as and for thepurpose described.

2. The means described for taking the cinders from pipe]? anddistributing them on the rails, consisting of the pipe J and box Khaving lateral pipes discharging in front of wheels, in the manner andfor the purpose set forth.
